Referring more particular y to the drawings, the same reference numerals designate similar parts throughout the several views.

In this exemplification of the invention the numeral 30 designates a suitable casing within which this improved apparatus is placed and said casing is provided with a removable front 31, which closes the upper portion thereof and the lower portion of the casing may be closed by a suitable gong or bell 32. Arranged within the casing 30, preferably the lower portion thereof, and supported by the rear Wall, are suitable operating motors, such as spring motors 33 or the like. These motors are preferably arranged one in advance of the other and as the specific construction and the operating mechanism of each motor is the same, the

individual indicators. Fig. 13 is a detail l detailed description of one will apply equally as Well to the other. Each motor is provided j of the casing is a member 47 for checking With an escapement Wheel 34, which is preferably provided with laterally projecting;

lugs or pins 35, which are suitably spaced from each other and arranged around the periphery of the escapeinent wheel or member 34. The shaft 36 of the front motor preferably projects beyond the front of the casing 3U and terminates in an angularly shaped extremity 37, by means of which l the spring of the motor may be wound when desired and the shaft 36L of the rear motor passes through the shaft 36 of the front motor and also extends beyond the front of the casing and terminates m an angular extremity 37 by means of which the spring of said motor may be wound independently of another motor, an ordinary pawl 38 and ratchet mechanism 39 being provided for each motor.

The front mechanism is provided With a release member or arm 40, which is pivotally supported adjacent one end, as at 4l, to the casing 30 and said release member or arm is preferably provided with an enlarged portion 42, preferably adjacent its point of pivotal support 41 and laterally projecting from said enlarged portion are spaced lugs 43, 44, which are preferably provided with flattened faces 45 and said lugs 43, 44, are so arranged with relation to each other and to the laterally projecting lugs or pins on the escapement wheel 34 that when the member or arm 4() is in its normal position to lock the escapement wheel 34 against rotation under the influence of the spring, the flattened face of the lug 43 will stand within the path of movement of the pin or lug 35. W hen the release member or arm 40 is moved about its point of pivotal support 41 to cause the lug 43 to move out of the path of the movement of the pin or lug 35, the lug 44 will assume a position in the path of movement of the release pin 35, which latter will then advance to engage and be arrested by the lug 44 to permit the escapement Wheel 34 to move a portion of one complete step of rotation and as the release member or arm 40 moves in the reverse direction the lug 44 will be moved out of the path of movement of the pin 35 which is in engagement therewith, to permit the said pin to pass between the lugs 43, 44 and permit the escapement wheel to move forward to complete the step of rotation. At the same time the lug 44 is being moved out of engagement with the in 35, the lug 43 will be moved into the pat i of movement of the next advancing pin or lug 35 to check the esca ement Wheel.

T e release arm or member 40 may be of any desired length suitable for the purpose, and its free extremity preferably terminates in a reduced portion 46. Pivotally mounted upon a suitable support, preferably the back or controlling the release member or arm 4U, and said member 47 is located adjacent the extremity of the release member or arm 40 and is provided with spaced projections 48 between which the reduced poi tion 46 of the release member or arm 40 is adapted to move and said checking or controlling member 47, together with the spaced projections 48, is so located with relation to the point of pivotal support 41 of the release member or arm 4() that during the operative movement of the latter, the reduced portion 46 will alternately engage one of the projections 48. 'l'he member 47 is prefer ably enla. ged as at 49 and is provided with spaced lips or ears 50, which are adapted to be alternately engaged by a later ally projecting pin or lug located on the adjacent portion of the release niember or arm 40 and said enlarged portion 49 is also preferably provided with a recessed portion 56 into which the pin or lug 55 is adapted to enter when the checking or conti olling member 47 is in its normal position and said pin or lug 55 is so arranged as to engage one edge of the recess 56 as the reduced portion 46 engages one of the spaced projections 48.

lrojecting from the checking or controlling member 47 is an arm or lever 57 and a suitable counterbalancing member 58. The arm or level` 57 is adapted to move in a guide 59 which is suitably ,supported preferably near the free extremity thereof, shown more clearly in Figs. 2, 3, 5 and 22. Y A slotted member 60 is pivotally mounted as at 61 to a suitable support and in close proximity to the guide 59 and said member 60 is so arranged with relation to the guide 59 that the slot therein will register with a slot in the guide 59. rlhe extremity of the arm or lever 57 also projects into the slot in said member 60, as shown more clearly in Figs. 3, 5 and 22. The member 60 prefer ably projects below its point of pivotal support 61, as at 62, and passing through said projection 62 is an adjusting or limiting screw 63 which is adapted to regulate the movement of the member 60. A dog or pawl 64 is pivoted to the member 60 in such a manner that the portion 65 thereof will project partially across the slot in said member and said extremity 64 is so located as to be engaged by and support the extremity of the arm or lever 57 to hold the flattened face 45 of the lug 44 on the extremity of the release member orrcam 4() in the path of movement of one of the pins or lugs 35 on the escapement wheel 34 when the member 60 is moved about its point of pivl otal support 61 in a position to cause the extremity 65 of the dog or pawl 64 to assume a position in the path of movement of the extremity of said arm or lever 57. A similar dog or pawl 66 is also pivotally supported by the member 60 and is preferably so arranged as to extend partially across the slot in said Y the arm or lever 57 when the member 60 is rocked about its point of pivotal support 61 to move the dog or pawl 64 out of engagement with said extremity and to permit the release member or arm 4U to be moved about its point of pivotal support 41 to cause the lug 43 to assume a position in the path of movement of one of the pins or lugs 35. 1f desired, the slot in the guide 59 may be reduced as at 67, shown more clearly in Fig. 5 of the drawing, tov prevent the extremity of the arm or lever 57 from springing away and to direct said extremity to a position to insure its engagement with the dog or pawl 66 when the latter is in operative position.

Any suitable means may be provided for moving the member 60 about its point of pivotal support 61. A suitable and efficient means for accomplishingl this purpose cornprises an electro responsive device such as a magnetic coil 63 or the like, and an armature 69 which preferably forms a portion of the member 60, and as the member 60 is oscillated by means of the armature 69 being alternately attracted by and released from the magnet 68, the pawls or dogs 64, 66, will be alternately moved into and out of the respective path of movement of the extremity of the arm or lever 57 to control the movement of the checking member 47, which in turn controls the movement of the escapement wheel 34.

The motor which is located adiacent the front of the casing is for the purpose of sounding the audible signal or striking the gong 32 and the said motors are preferably spaced from each other by means of a suitable frame 70, shown more clearly in Fig. 5 of the drawings, and arranged adjacent the gong or bell 32 is another suitable supporting frame 71, to which latter frame a hammer 72 is pivotally supported preferably by one extremity, as at 73, shown more cleaily in Figs. 1, 2, and 5 of the drawings. This hammer 72 is preferably provided with a projecting ear 74 and pivotally supported by said ear is a bail 75. A yielding member 76, such as a spring or the like, is secured preferably to the supporting frame 71, shown more clearly in Fig. 5 of the drawinf-'s, and one extremity of said member is preferably seated within and connected to the hammer 72 by means of the bail 75, and said member 76 serves as the means for forcing1 the hammer 7 2 to strike the gong or bell 32. Any suitable means may be provided for adjustina the tension of said yielding` member 76 with relation to the hammer 72 and a suitable and efiicient means for accomplishing this purpose comprises an adjusting screw or bolt 77 which preferably extends through the ear 74 and engages said member adjacent the bail 75. if desired, a suitable lug or bolt 7 8 may also be provided which is preferably secured to the supporting frame 71 in such a manner as to engage and rest against the yielding member 76 to brace said member and increase its rigidity.

The hammer 72 is preferably provided with a hub 79 which is located preferably adjacent the periphery of the escapement wheel 34 and said hub 79 is provided with a cam-shaped portion 8O and said hub is of such a length that when the hammer 72 is in position, the cam-shaped portion 80 will be ocated on the opposite side of the escape-k ment wheel 34 and will stand a sufficient distance from the hub that when the escapement wheel 34 is rotated, the pins or lugs 35 will engage the cam-shaped portion 80 to rock the hammer 72 about its point of pivotal support 73 to carry the hammer into such a position that when the engaging pin or lug 35 is moved into a position to release the cam-shaped portion 80, the yielding' member 76 will throw the hammer 72 forcibly against the gong or bell 32 to strike the latter. The hammer is also provided with an ear or projection 8l, located at any convenient point. A handle or lever 82 is pivotally supported preferably by means of a hub 83, which is journaled adjacent the hub 79 and said handle or lever 82 is provided with a lateral projection 84 which is adapted to engage the ear or projection 81. The hammer 72 when in an operative position is adapted to be intermittently moved by means of the respective pins or lugs 35 and the handle 82 is adapted to be secured into such a osition as to permit the movement of the iammer 72 under the iniiuence of the pins or lugs 35. Any suitable means may be provided for securing` the handle or lever 82 in an inoperative position. A suitable and efficient means for accomplishing this purpose comprises a member 84a provided with shoulders 85, 86. The extremity of the handle 82 preferably projects through the casing 30 and the shoulders 35, 86 are so disposed that when the extremity of the handle 82 is in the position as shown in Fig. 17 of the drawings, that is, engaging the shoulder 85, the lateral projection S4 thereon will be locked out of engagiement with the ear or projection 81 to permit the free operation of the hammer 72, but when the handle is shifted to engage the shoulder 86, the proiection 84 will engage the ear or proiection 31 to rock the hammer about its point of pivotal support, and the coperating` parts will be moved out of the path of movement of the pins or lugs 35 which will permit the escapement wheel 34 to rotate without impartingr motion to the hammer 72. The hammer is adapted to be moved or shifted to this point when it is desired to send or receive a still alarm.

Any suitable and ecient means may be provided for displaying the nature of the audible alarm received by the apparatus, such, for instance, as a fire alarm. A suitable and efficient means for imparting this information comprises a sign 87 which is adapted to be moved so as to be displayed through a suitable opening preferably in the upper portion of the front of the casing and said sign is preferably pivoted to one extremity of an arm 88, which latter is also preferably pivoted to a suitable support 89. The sign 87 may also be provided with depending arms or projections 90 which serve to counterbalance this sign and act as guides for maintaining the sign in a proper position. The arm 88 is of such a length that when moved about its point of pivotal support 91, the sign 87 will be raised.

Any suitable and efficient means may be employed for raising the sign, but a simple and eliicient means comprises a pivotally supported member 92, which is preferably located adjacent and above the periphery of the escapement wheel 34, as shown more clearly in Figs. 1, 2, 5 and 21, and said member 92 is provided with a depending portion 93, which normally stands within the path of movement of the pins or lugs 35 on the escapement wheel so that when the escapement 34 moves one step of rotation one of the pins 35 will engage the adjacent extremity of the depending portion 93 to rock the member 92 about its point of pivotal support. The member 92 is also preferably rovided with a projecting arm 94, which is ocated preferably substantially diametrically opposite to the depending portion 93 and said arm 94 is connected to the arm 88 by means of a suitable link or connection 95 so that when the member 92 is rocked about its pivot, the link or connection 95 will move the extremity of the arm 88 which is connected to the sign 87 to such an extent as to cause the sign to be displayed through the opening in the casing.

The sign 87 will be moved into view by the irst pin or projection 35, which engages the depending portion 93 of the member 92, that is, the sign will be displayed by one step of rotation ofthe escapement wheel and after having been thus adjusted, it is held in its adjusted position until released in the manner to be set forth. A suitable and efficient means for locking or holding the sign in an exposed position preferably comprises a stop 96, which extends into the path of movement of the arm 88 and is adapted to be engaged by said arm when said arm has substantially reached the limit of its movement. A dog 97, preferably spring controlled, is pivotally supported adjacent the stop 96 and the extremity 98 of the dog is adapted to normally project into the path of movement of the arm 88 so that when the arm 88 is raised,

said extremity 98 will be engaged by and moved out of the path of movement of the arm 88 to permit said arm to continue in its movement until it strikes the stop 96 at which time the dog 97 will assume its normal position causing its extremity 98 to move into the path of the return movement of the arm so that the arm will be locked into position and supported by the extremity 98 of the dog 97, which will also hold the depending portion 93 of the member 92 out of the path of movement of the pins or lugs 35 on the escapement wheel 34. The dog 97 is preferably provided with an extension or arm 99 by means of which it may be rocked about its point of pivotal support to release the sign 87 and when so released, the sign will move into a concealed position by means of the gravity thereof together with the gravity of its operating parts.

A suitable and efiicient means for rocking the dog 97 to release the sign comprises an operating bar or member 100, one end of which is preferably pivotally connected to a member 101, which is pivotally supported by means of a suitable frame 102 and said member 101 is located preferably above and adj acent the escapement wheel 34 of the rear motor. Said member 101 is provided with a downwardly projecting ear or portion 103 which is adapted to assume a position in the path of movement of the lugs or pins 35 so that as the escapement advances one step of rotation, the projection 103 will be engaged and raised, thereby rocking the member 101 to draw the bar or member downward. This bar or member 100 is provided with a proj ection or shoulder 104 which is located adjacent and slightly above the projecting portion 99 of the dog 97 so that when the bar or member 100 is drawn downward, the projection or shoulder will engage the extension 99 and rock the dog 97 to move the extremity 98 out of engagement with the arm 88.

It will be apparent that although the hammer 72 is adjusted to an inoperative position for a still alarm, the front device will be operated just the same to display the sign 87 when a fire alarm is sent in and the number of the box may then be obtained from the visual signal of the rear device.

The rear motor controls the visual signal and is operated in the same manner as the front motor which operates the audible signal and both of said motors are released or controlled by the electro-responsive devices 68. The circuit being first completed through the magnets 68 of the rear motor will start said motor to operate and by the time the rear motor stops the circuit through the magnet of the front motor will be controlled in the manner to be set forth, which will set the front motor in operation. The magnets 68 may be supported in any suitable manner and if desired they may be supported by @messes .3 means of a pivoted arm 105v which may-be adjustably held in position by means of a screw or bolt 106 so as to adjust the magnets or to accommodate magnets of diiferent sizes and may be held in their adjusted position by means of suitable stop screws or bolts 107 provided with the ordinary jam nut 108. The magnets may also be supported for rotative adjustment with relation to the arm 105 by means of an axle 109, which is journaled in one extremity of the arm and which is secured to the magnets and said axle may be secured against rotation by means of a suitable screw or bolt 110.

If desired, suitable' means may be provided for securing arecord of the alarms received. A suitable and efficient means comprises a tape or strip 111 wound upon a suitable spool 112 and said spool is supported in any suitable manner such as by means' of brackets 1 13 preferably on the exterior of the casing 30. The tape or strip 111 is adapted to pass through a suitable slot or aperture 114 in the casing between suitable guide rollers 115 and between guide plates 116 preferably located on the inside of the casing. These guide plates 116 are preferably provided with registering apertures 117. Vtivrotally supported adjacent the aperturesA is a guide 1 18 through which passes a perforating pin'or needle r119 and an arm 120'is preferably pivoted between its extremities to a suitable support 121 and one extremity thereof is pivotally connected to the perforated pin or needle 119 so that when the free end of the arm 120 is moved about its point of pivotal support, the extremity of the perforating pin or needle 119 will be first moved out of engagement with the strip 111 and a continued movement of the arm 120 in the same direction will rock the guide 118 on its pivot so as to advance the pin or needle 119 toward the supply end of the strip 111 and when the arm 120 is moved in the opposite direction, the point of the pin will perforate the strip and will remain in contact therewith during the movement of the guide 118 about its pivot to feed the strip 111. The arm 120 may be operated in any desired or suitable manner but a simple and efcient means for accomplishing this purpose comprises a link 123, one end of which is pivotally connected to the free end of the arm and the other end has a pivotal connection with the release member or arm 40 so that when the latter is moved about its point of pivotal support, movement will be transmitted to the perforating pin or needle 119. The free end of the strip 111 may pass out of the casing through a suitable slot 124, as shown 'more clearly in Fig. 1 of the drawings.

The visual signal is located in the upper portion of the casing 30 and comprises a series of independent numbers or characters arranged in separate groups and each of said groups is provided with'an independentoperating mechanism, that is, with independent means for controlling or moving the res pectiveV numbers into view. The operating mechanism of all of said groups Ybeing of the same construction, the detailed description of one group will apply equally as well to the others. Each group preferably comprises a series of nine members 125 mounted for'independent pivotal movement about a support 12,6. (See Fig. 6). These members are each provided with a series of teeth 127 disposed around the point of pivotal support 126. The normal position of these members 125 is to conceal said members and when moved about their points of pivotal support 126 the respective members will be moved into view. Any suitable means may be provided for moving these members 125 and a simple and efficient means for accomplishing this purpose comprises a pivotally supported segment 128, which is provided with a series of teeth 129 adapted to mesh with the teeth 127 on the members 125 and when the segments are rocked about their point of pivotal support 130, the members 125 will be moved about their points of pivotal support through the medium of the interengagmg .teeth 127, 1'29. Eachjsegm'ent 128-is preferably off. a composite yconstruction ycomprising the seg-f ment 128 proper, to each side of which issecured plates 131 which are preferably of a somewhat larger construction than the segment so as to form a space beyond the periphery of the segment and between the plates 131. The members 125 are so spaced fromeach other that when the teeth 129 of the respective segment are in engagement with the teeth 127 of the member 125, the plates 131 will stand between or project into the spaces between the portions of the members 125 adjacent the pivot 126 and serve as means for guiding the segments and for preventing displacement thereof.

The segments 128 are successively moved about their points of pivotal support 130 in any suitable manner, preferablyT by means 0f a cylindrical member 132 rotatably supported adjacent the segments and said cylindrical member is provided witha plurality of spaced peripheral cams 133 and said cams are so arranged with relation to the adjacent extremity of the segments 128 that one cam will be in proximity to each segment. The numbers on the members 125 are preferably arranged so as to progress from 1 to 9 in a direction from the rear toward the front of the casing and the cams 133 on the cylindrical member 132 are so arranged with relation to the segments and are so constructed that during the first step of said cylindrical member, the cam adjacent the number 1 will move said number into view. A further rotation of the cylindrical member in the same direction will cause the second cam, or the cam adjacent the member bearing the number 2, to move said member into view and so on causing the numbers to be exposed according to their direction of progression; the cam 133 adjacent the numeral 1 being larger or of greater circumference than the cam adjacent the numeral 9. rlhe members 125 having been once moved into position to expose the respective number'thereon, will be held in position by the cams until released in the manner to be set forth, which Will permit all of said members which have been exposed to return to their normal or concealed position. A portion of the periphery of the cylindrical member 132 is free from a cam-shaped projection, as at 134, shown more clearly in Figs. 6 and 7 of the drawings, and extends substantially the entire length of the cylindrical member 132, and when said portion 134 is adjacent the extremities of the segments 128, said segments will assume a normal position to permit the members 125 to be returned or concealed. A suitable spring 135 may be provided for each of the segments 128 to cause them to return to their normal position and said spring preferably rests Within the space formed between the plates 132 of the segment.

'l he cylindrical member 1,32 is preferably provided With a toothed or ratchet wheel 136, which is secured to one extremity of theaxle thereof by means of which said member may be intermittently rotated. Any means may be employed for imparting motion to the member 132 and a suitable and eliicient means for accomplishing this purpose comprises an electro-responsive device such as a magnet or the like, and an armature 138, which is adapted to be controlled by the magnet when the latter is energized. A bar or member 139 is operatively connected to the armature 138 and pivotally supported by the free end of said bar or member 139 is a yielding dog 140, which is provided with a projecting portion 141 adapted to engage the bar or member 139 to limit the movement of said dog in one direction and to permit its free movement in the other direction. rl he extremit y of said dog or member is adapted to stand in close proximity to the teeth or ratchet wheel 136 so that when the magnet 137 is energized and the armature 138 is attracted thereby, the dog 140 Will be brought into engagement with one of the teeth 136 and a continued movement of said arm 139 in the same direction will advance or rotate the cylindrical member 132 one step of rotation and when the magnet 137 is denergized the armature 138 will return to its normal j position and the dog 140 will move about its point of lpivotal support to permit the same i to pass t e next tooth 136 to assume a posii tion to engage said tooth to move the cylindrical member 132 another step of rotation When the bar or member 139 is again moved by the attraction of the armature 138. A

suitably pivoted dog 142 is adapted to be moved into engagement with the teeth 136 as the cylindrical member 132 is rotated by means of a spring 143 to prevent a retrograde movement of the cylindrical member as the dog 140 is returned to its normal position.

'lhe various groups of members 125 are operated independently of each other and successively, that is, the members designating the first number or digit of the alarm received will be first displayed and held in position in the manner already described, a'fter which the numbers or digits indicating the second numeral of the alarm will be displayed and so on until all of the numbers or the complete number of the box from which the alarm has been turned in has been displayed. lhe pawls or dogs 142 of all of the groups may be simultaneously released in any desired or suitable manner. A simple and efficient means comprises a bar or member 144, which is suit ably supported and connected to an armature 145 through the medium of a pivoted arm 145a7 the armature being controlled by a suitable electro-responsive device 146 which operates independently of the electro responsive devices, 137. The bar or member 144 is provided with projecting portions 147 so arranged that one-of said projections will be located in close proximity to a projecting portion 148 on each of the retaining dogs or pawls 142 so that when the armature 145 is attracted by the magnet 146, the arm 145L will be rocked to move the bar or member 144 in a direction to rock the dogs or retaining pawls 142 about their points of pivotal support so as to move the extremities thereof out of engagement with the teeth 136 of the ratchet wheel on the cylindrical member 132. When thus released, the cylindrical members 132 may be returned to their normal position in any desired or suitable manner preferably by means of a spring 149, one end of which is secured to a suitable support and the other end to an arm 150.

'l he numbers in the groups are successively displayed and referring to Fig. 6 ofthe drawings, the numbers in the roup in the upper left hand corner will be rst displayed and then the numbers in the upper right hand group will next be displayed followed by the num ers in the lower left hand group, and iinally the numbers in the lower right hand group, the current being completed through the electro responsive devicein the upper left hand corner of Fig. 10 from where it is switched to the electro responsive device in Y the upper right hand corner of said iigure, then to the electro responsive device in the lower left hand corner and then to the electro responsive device in the lower right hand corner and finally to the release electro responsive device located in the middle of the ligure.

Any-meansmay loe-,provided for completing the currents through the various electro p responsive devicesand a simple and efficient cient means for accomplishing this purpose comprises a hooked arm or member 158 which is s: itably s1' pported in such a position that the hooked-shaped portion thereof will engage one of a series of teeth 159 on the switch 151 each time the arm 158 makes a complete movement and move said switch one step so as to engage the next contact to send the current through the next electro responsive device to energize the same. Any means may be provided for moving the arm 158. A suitable and efficient means for accomplishing this purpose comprises a spring motor 160, which is geared up to a siitable worm-screw 161. A member 162 is pivotally supported preferably adjacent the worm-screw 161, and to said member 162 is connected one extremity of the rod or bar 100, as shown more clearly in ligs. 9, 14 and 16. Said member 162 serves as a spport for a laterally movable arm 163 wlich is also pivoted to the member. The free extremity of the arm is pivotally connected to the hooked-arm 158 and depending from said arm 163 preferably at the point of connection with the arm 158 is a pin 164, which is adapted to stand within the space between the threads of the screw 161 and said screw 161 tends to move the arm 163 through the medium of the pin 164 so as to cai se the hooked-arm 158 to engage one of the teeth 159 of the switch 151 to move the latter. A s' itable projecting pin 165 may be provided at a s' itable point within the length of the screw 161 to be engaged by the pin 164 to stop the advancement of the pin 164 by the thread of the screw, to stop and lock the motor. A spring 166 is provided for holding the pin 164 at the front end of the screw 161 so as to hold the arm 158 in a position to engage one ofthe teeth 159. As soon as the current is completed through the rear apparatrs and its motor is released to operate the apparati` s,

the bar or rod 100 will be vibrated as the -escapement 34 rotates in the manner as first Yberaised-from its normal position in contact with the pin 165 to release the motor 160, and moved to the front end of the screw by the spring 166 and rlowered into engagement with the threads of the screw after which it will be alternately raised and lowered so as to be intermittently moved out of engagement with the threads of the screw 161 to prevent said screw from feeding the pin 164 towards its opposite end, which would shift the switch, but as soon as the escapement wheel 34 has stopped rotating the bar or rod 100 will be held still and the screw 161 will feed the pin 164 towards its opposite end, which will raise the arm 158 to shift the switch 151. During this portion of the operation the current will be traveling through the electro responsive device of the first group. When the switch is thus shifted and is in engagement with the contact 154, the current will be shifted from the first electro responsive device to the second and as the switch moves from one to the other of the contacts, the current will travel through the successive devices until the switch is in engagement with the contact 157, which will place the parts in a position to send the current through the release electro responsive device and when the end of the arm 158 reaches the limit 'of its movement, it will engage a suitable switch 169, shown more clearly in lig. 9, and the diagrammatic lig. 25, to complete the circuit through said release device.

The arm 158 closes the switch 169 each time it makes a complete movement but has no effect upon the current until the switch 151 is in engagement with the contact 157 and when the switch 169 is then closed the current will flow through said device. The current flowing through said device will release the cylindrical members 132 in the manner already set forth7 so that the springs 149 will cause the arms 150 of all of the cylindrical members 132, except the cylindrical member which controls the operation of the numbers in the first group, to engage the respective stops 167. The switch 151 is provided with an arm 168 which moves with the switch and during 'the movement of the switch 151 said arm 168 is moved into a position to be engaged by the arm 15() on the cylindrical member 132 on the first group and when the arm-150 engages the arm 168, it will move the switch 151 back to its normal position or in engagement with the contact point 153.

Any suitable means may be provided for sending an alarm or signal to a point remote from the apparatus when an alarm is turned in and the apparatus begins to worl. This may be accomplished by means of a separate circuit designated generally by the reference numeral 170, shown more clearly in Figs. 1, 2, and 3 of the drawings. A suitable switch may be arranged within the casing and supported in any suitable manner for controlling or closing the circuit 170. This switch preferably comprises stationary contact point 171 and a pivotally supported spring controlled member 172. This member 172 is preferably provided with a yielding dog 173 and said member 172 is adapted to be normally locked or held out oi engagement with the contact 171 and suitable means may be provided for automatically releasing the member 172 to permit the spring 174 to move the member into engagement with the contact 171 to close the circuit.

A suitable and efficient means for locking and releasing the member 172 preferably comprises a pivoted member 175 and said member is provided with a biiurcated portion 176 into which the release member or arm 40 is adapted to stand and the bifurcated portion 176 is so located with relation to the release member or arm 40 that when the latter is moved about its point of pivotal support 41, the member 17 5 will also be moved about its point of pivotal support 177. This member 175 is also provided with a hook-shaped portion 178 and an overhanging or projecting lip 179 to produce a slot 180, which has an opening 181 between the extremity of the hook-shaped portion 178 and the over-hanging lip or portion 179 and said slot is so positioned with relation to the yielding dog 173 that when the member 172 is out of engagement with the member 175 and is moved about its point of pivotal support the extremity of the dog 173 will engage the outer iace of the hook-shaped portion 178, which latter will move the dog about its point of pivotal support and as the member 172 is moved further in the same direction, said dog will pass out of engagement with the hook-shaped portion 178 and spring into the slot 180 which will lock the member 172 in the position shown more clearly in Fig. 3 of the drawings to break the circuit 170.

When the motor which controls the releasing member or arm 40 starts to operate, the latter will also be operated and will rock the member 175 about its point of pivotal support. The normal tendency of the spring 174 is to cause the member 172 to move towards the contact 171. As the member 17 5 is rocked by the vibration of the release member or arm 40 the dog 173 will remain in engagement with the inner face of the hook-shaped portion 178 until the tip or nose of said hook-shaped portion passes out of engagement with the dog. The dog being thus released, the member 172 will be thrown in the direction towards the contact 171 so that the dog will engage the inner face ci the overhanging lip or profection 179 and will remain in contact with said Jface during the movement of the member 175 in the opposite direction and until the extremity of the overhanging lip or portion 179 passes out of engagement with the dog. The member 172, being thus released, will move under the inluence of the spring 174 into engagement with the contact 171 to complete the circuit and said circuit will remain completed until the member 17 2 is moved out oi engagement with the contact 171 and as the vswitch is located within the apparatus and at a point remote from the place where the signal is placed, the current cannot be broken except at the apparatus.

Any suitable means may be provided for breaking the circuit or moving the member 172 out of engagement with the contact 171. A suitable and efiicient means for accomplishing this purpose comprises a spring controlled rod 182 which extends into the casing 30 and said rod is preferably provided with a button 183 on the outside of the casing, so that when the button 183 is pressed, the extremity of the rod 182 will engage and move the member 172 about its point of pivotal support to cause it to be locked out of engagement with the contact 171 in the manner already set forth. Within the casing 30 is a stationary sign 184a which is displayed through the front thereof when the sign 87 is lowered as shown in Fig. 1, so that when the audible signal is not operated this sign will be always displayed, but when the audible signal is operated, the sign 87 will be moved to a position to be displayed and to cover the sign 184% The circuits of the various electro responsive devices will now be described and for this purpose reference vmay be had to the diagrammatic illustration shown in Fig. 25 of the drawings. In this diagrammatic illustration, the reference characters A and B represent street boxes from which the alarm may be turned in, C designates the electro responsive device which controls the rear apparatus for displaying the individual numbers and D designates the electro responsive device for controlling the front apparatus for operating the gong or audible signal. The letters E, F, Gr and H designate respectively the electro responsive devices for successively controlling the visual signals or the members 125, and I designates the electro responsive device for controlling the releasing mechanism for the members 125. In this exempli'lication of the invention, the electro responsive device C, which controls the rear apparatus for operating the visual signal, is preferably placed upon a grounded or normally open circuit and is arranged to respond more quickly than the front device to start the rear apparatus in advance of the front apparatus. The battery K is arranged in the grounded circuit and the battery L is arranged in the metallic circuit and by placing these batteries in such a position as to be
